for telling which number is greater, which one is greater 99.9% or 1 ???

Answers

Answer:

99.9%

Step-by-step explanation:

1⇒ 1×10^0

99.9 % ⇒ 999*10^-1

1:999*10^-1

10:999

Therefore it is clear that 99.9% is greater

99.9%
So it is greater bc on a pie graph, it shows more and it will always be greater… doesn’t matter if it still needs the +1%

In February of 2006, there was a
record snowfall of 26.9 inches in one
day in New York City. The normal
snowfall for the month of February in
New York City is 8.5 inches and March
is 5.1 inches. How much more snow
fell in the one day storm in 2006 than
normally falls in February and March
combined

Answers

Answer:

13.3

Step-by-step explanation:

Since 8.5 fell in February and 5.1 fell in March. We can add these two numbers together to see what the total is combined normally.

8.5 + 5.1 = 13.6

The record was 26.9, so we'll take this number and subtract it from 13.6 to see how much more fell in one day than the normal

26.9-13.6= 13.3

X = 69

Step-by-step explanation:

You add the 11x and 58

Answer: hope this helps ♡      (i wont mind getting brainliest )

x = 3

Step-by-step explanation:

z° and 89° are two opposite angles.

z° = 89°

89° + 89° + (11x + 58)° + (11x + 58)° = 360° (adds up to 360° coz its a circle)

178° + (11x + 58)° + (11x + 58)° = 360°

178° + 58° + 58° + (11x + 11x)° =  360°

178° + 116° + 22x° =  360°

294° + 22x° = 360°

294° - 294° + 22x° = 360° - 294°

22x = 66

22x ÷ 22 = 66 ÷ 22

x = 3

(double check: 11×3 = 33    2×(33+58)+178=360° ✓)

The diagonal of a television measures 27 inches. If the width is 22 inches, calculate its height to the nearest inch.

Answers

Answer:

16 inches

Step-by-step explanation:

We can use the Pythagorean theorem to find the height of the television. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two smaller sides is equal to the square of the length of the longest side (the hypotenuse). In this case, the diagonal of the television is the hypotenuse and the width and height are the other two sides.

So, we can set up the equation as follows:

a^2 + b^2 = c^2

where a is the width (22 inches), b is the height, and c is the diagonal (27 inches).

We can solve for b:

b^2 = c^2 - a^2

b^2 = 27^2 - 22^2

b^2 = 729 - 484

b^2 = 245

b = √245

b = 15.56 inches (rounded to two decimal places)

So, the height of the television to the nearest inch is 16 inches.

Answer:

Your answer will be 72.

Step-by-step explanation:

You add the two numbers that you are given. This will get you 108. Next you subtract that from 180. 180-108=72

72 because 52+56 is 108 degrees while a triangle should have 180 so you 180-108

If a value of 60° is added to the data, how does the median change?

Answers

Answer:

The original data set:

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

Finding the median:

77 and 82 are the 2 middle numbers

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

Do 77 + 82 which equals 159

Then do 159 ÷ 2 which would be 79.5

The median for the original data set would be 79.5

Then adding the 60° would make a new data set:

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

The middle number would be 77

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

So the median for the second data set would be 77.

Step-by-step explanation:

Hope this helps you a little, you're welcome

Step 1: find the original data set.

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

77 and 82 are both the middle numbers

Step 2: add the two middle numbers

77 + 82 = 159

Step 3: divide your sum by 2.

159 divided by 2 equals to 79.5

The median for the original data set would be 79.5.




For the new data set, you add 60 to the data set.

Step 1: find the new data set

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105.

Step 2: find the middle number.

The middle number is 77.

The median for the new data set is 77.

There are two numbers. The first number minus the second number is 15. one-third of the sum of the numbers is one quarter of the first number. what are the numbers?

Answers

Answer:

First number: 12

Second number: -3

Step-by-step explanation:

First, let's establish some variables:

x= first number

y= second number

Now, let's turn what is told to us into equations:

The first number minus the second number is 15

  x - y = 15

One-third of the sum of the numbers is one quarter of the first number

 1/3 ( x + y ) = 1/4 ( x )

Now, let's use the first equation given to us to find x in terms of y:

x - y = 15     [Add y to both sides]

x = y + 15

Next, we will take the value of x we found and plug it into the second equation:

1/3 ( x + y ) = 1/4 ( x )     [Plug in x]

1/3 ( {y + 15} + y ) = 1/4 ( {y + 15} )     [Combine like terms]

1/3 ( 2y + 15 ) = 1/4 ( {y + 15} )     [Distribute on both sides]

(2/3)y + 5 = (1/4)y + 15/4     [Subtract 15/4 from both sides]

(2/3)y + (5/4) = (1/4)y     [Subtract (2/3)y from both sides]

5/4 = (-5/12)y     [Multiply both sides by -12/5]

-3 = y

Since we have now found the value of y, let's plug it into our first equation to find the value of x:

x - y = 15     [Plug in y]

x - (-3) = 15     [Simplify]

x + 3 = 15     [Subtract 3 from both sides]

x = 12

So, our first number must be 12 while our second number is -3.

If this answer helped you, please leave a thanks or a Brainliest!!!

Have a GREAT day!!!

Answer:

-12 and 3

Step-by-step explanation:

Let first no. be x

First number - Second number = 15

So, x - 2nd no. = 15

Second number = 15 + x

First number = x

Now, One-third of the sum of numbers is = [tex]\frac{x+(15+x)}{3} = \frac{15+2x}{3}[/tex]

One-quarter of first number = [tex]\frac{x}{4}[/tex]

Now,

[tex]\frac{15+2x}{3} = \frac{x}{4}[/tex]

= 4(15+2x) = 3x

= 60 + 8x = 3x

= 60 = -5x

= -12 = x

Hence, First number = -12

Second number = -12 + 15 = 3

Check:

[tex]\frac{15-24}{3} = \frac{-12}{4}[/tex]

= [tex]\frac{-9}{3} = -3[/tex]

= -3 = -3

Hence, proved!
